Layered double hydroxides (LDHs) consist of layers with two or three positively charged metal ions surrounded by hydroxide ions, water molecules and partially or fully hydrated exchangeable charge-compensating anions between the layers. These materials have many application possibilities. In thi...

The crude polysaccharide was extracted from Grateloupia lithophila through hot-water extraction and deproteinization. Further, fractionated by anion-exchange column using Q-Sepharose and purified by gel-permeation chromatography using Sepharose 4-LB column. The crude and purified polysaccharide ...

The sulfated rhamnose polysaccharides found in Enteromorpha prolifera belong to a class of unique polyanionic polysaccharides with high chelation capacity. In this study, a complex of sulfated rhamnose polysaccharides with chromium(III) (SRPC) was synthesized, and its effect on type 2 diabetes m...

UDP-rhamnose is synthesized by UDP-rhamnose synthase, but the reaction requires two kinds of cofactors, NAD+ and NADPH. In this work, a cofactor self-sufficient UDP-rhamnose regeneration system was described herein. The UDP-rhamnose synthase (VvRHM) gene from Vitis vinifera was cloned and expres...

Tuberculosis is one of the leading causes of death from bacterial infections. The multi-drug resistant strain has warranted the development of new drug molecules which can inhibit the growth of Mycobacterium tuberculosis (M.tb). Most of the known drugs inhibit the enzymes in the cell wall biosyn...

Toluene-o-xylene monooxygenase (ToMO) from Pseudomonas stutzeri OX1 was found to oxidize nitrobenzene (NB) to form m-nitrophenol (m-NP, 72%) and p-NP (28%) with an initial rate of 0.098 and 0.031 nmol/(min mg protein), respectively. It was also discovered that wild-type ToMO forms 4-nitrocatecho...

A new imine derivative, (E)-4-chloro-2-((4-methoxybenzylidene)amino)phenol has been synthesized from the reaction of 4-Anisaldehyde with benzoyl 2-Amino-4-chlorophenol. The results of a combined experimental and DFT investigations of the structural and spectroscopic properties of the title compo...

In this work, the nematic liquid crystal (LC) N-(4′-methoxybenzylidene)-4-n-butylaniline (MBBA) was prepared and doped with different concentrations (0.025, 0.05, 0.06, 0.07, 0.08, and 0.1 wt.%) of multi-walled carbon nanotubes (CNTs) at room temperature to study the electric properties of (LC–...

A convenient and facile synthesis of t-butyl-2-(4-hydroxy-3-methoxybenzylidene)hydrazine carboxylate (1) was accomplished by refluxing t-butyl carbazate with an appropriate aldehyde in ethanol. The resulting compound was characterized using spectral data analysis augmented by X-ray. Single cryst...
